Step-Up SIP Calculator
Most people earn more as their careers progress, so a SIP that stays flat gradually becomes a smaller share of income. A step-up SIP increases the monthly amount by a fixed percentage every year. This calculator shows the corpus a step-up SIP could build, the instalment you would be paying in the final year and how much extra you gain compared with a flat SIP of the same starting amount. Mutual fund investments are subject to market risks; the return is an assumption.
How to use the step-up sip calculator
- Enter the starting SIP, the expected return and the period.
- Enter the yearly step-up — for example 10% if you expect your income to grow at a similar rate.
- Compare the maturity value with and without the step-up.
- Check the final-year instalment to be sure it stays affordable.
Formula
The instalment is multiplied by (1 + step-up%) at the start of each new year. Each month: value = (previous value + instalment) × (1 + i), with monthly rate i = annual rate ÷ 12. The flat-SIP comparison uses the same starting amount with no increase.
Worked examples
₹10,000 rising 10% a year for 15 years
With a 12% return the corpus is ₹86,83,849.43 against ₹50,45,760.00 for a flat SIP — an extra ₹36,38,089.44. The final-year SIP is ₹37,974.98.
A gentler 5% step-up
At 5% a year the corpus is ₹65,30,751.93.
No step-up
With a 0% step-up the result equals a flat SIP, and the extra corpus is ₹0.00.
Practice problems
Try these yourself first, then check your answer. The answers come from the calculator above.
- ₹8,000 a month rising 8% a year for 20 years at 11%. What is the corpus?
Show answer
Maturity value with step-up: ₹1,21,95,191.78 · Estimated returns: ₹78,02,043.21 · Extra corpus from stepping up: ₹52,06,607.35
Common mistakes to avoid
- Choosing a step-up that outpaces your income and becomes unaffordable.
- Forgetting the final-year instalment, which can be much larger than the start.
- Treating the assumed return as certain.
- Stepping up only when you remember. Set it up with your fund house if they offer an automatic top-up.
- Ignoring inflation.
